Lots of ten second cars with no power adders, especially bigger cubes and roller cams.
Decent aftermarket aluminum heads are all over the place nowadays, Indys, Edelbrocks, etc..... Stroker kits are easy to get, especially the very popular 4.15 stroke stuff.
The trans should have a billet front drum IMO, as well as the usual upgrades, 4.2 lever, sprag, etc... shields are avaliable aluminum or composite, both are tight fits in most production floored cars.
Gears depends on your engine, trans and tire height etc...
Clutch has dipped into the 9 second club with his naturally aspirated no power adders big block..... TRUCK. It's not a full on race truck either.
